A dominant allele that causes a form of muscular dystrophy is known to be 80% penetrant. 100 children are born to parents having the following genotypes: Mm X mm. How many of these children do you expect will have this type of muscular dystrophy? Describe how you came to this number. What is one possible explanation for the reduced penetrance (HINT: the answer to this last part of the question can be fairly general)?

    Assume that tail length in mice is a quantitative trait involving two genes, each with 2 alleles. One allele at each gene contributes to long tails, the other allele at each gene does not (small tails). The genes are located on different autosomes. Mice with 0 contributing alleles have tails that are 4 cm in length; mice with tails with 4 contributing alleles are 12 cm in length. Determine the phenotypic ratio from an F2 from a true breeding parent...

    3. Sickle-cell disease is a genetic condition caused by an autosomal recessive allele which al- fects one in every 500 African American children born in the U.S. One in every ten African Americans is a carrier for the recessive allels. Although sickle cell disease is caused by a single human gene, it is expressed through many different effects throughout the body. The presence of a recessive sickle-cell allele in humans causes the red blood cells to produce abnormal hemoglobin protein...
